Varicose veins are usually caused by weakness in the walls and valves of the veins. Inside the veins are small one-way valves that open to let blood through and then close to prevent it from flowing backwards. Sometimes the walls of the veins stretch and lose their elasticity, causing the valves to weaken. Weak or damaged valves can cause varicose veins.
